forward osmosis (fo) has recently drawn attention as a promising membrane based method for seawater and brackish water desalination. in this study, we focus on the use of calciun chloride (cacl2) and potassium bicarbonate (khco3) as inorganic salt draw solution candidates due to their appropriate performance in water flux and reverse salt diffusion as well as reasonable cost. the experiments we...
Pembentukan propil asetat didapatkan melalui reaksi esterifikasi antara propanol dengan asam asetat. Reaksi termasuk dalam reversible sehingga penambahan katalis atau pengguanaan ekses pada salah satu reaktan dapat menggeser ke arah produk. ChemCAD digunakan untuk membantu simulasi proses menggunakan reaktor jenis ekuilibrium. Fitur sensitivity study mengetahui perbandingan mol umpan yang terba...
Polyphenolics and sugar are the components of many fruit juices. In this work, the performance of ultra-filtration (UF) for separating phenolic compounds from apple juice was studied by performing batch experiments in a membrane module with an area of 0.1 m and fitted with a regenerated cellulose membrane of 1 kDa MWCO. The effects of various operating conditions: transmembrane pressure (3, 4, ...
The goal of this research is preparation, optimization and in-vitro evaluation of rifampin-loaded silica nanoparticles in order to use in the pulmonary drug delivery. Nanoparticles are exhaled because of their small size. Preparation of nanoaggregates in a micron-size scale and re-dispersion of them after deposition in the lung is an approach to overcome this problem. We used this approach in o...
Bulk density is an important process parameter for machines that transport, feed or process granular materials. Certain process variables have been shown to increase bulk density, such as the channel geometry at machines with rotational helical elements, the shape, dimensions and dimension distribution of granules, pressure, temperature, and vibration of the granular layer. The effect of the ra...
In the paper a genetic algorithm for feed rate profiles synthesis is proposed. An E. coli fed-batch fermentation process is considered. The feed rate profiles based on three different lengths of chromosomes are synthesized. A satisfactory result for the fermentation system due to economical effect and process effectiveness is achieved.
−A comprehensive parametric study for a Fischer-Tropsch (FT) synthesis process has been conducted to investigate the relation between process parameters and reactor characteristics such as conversion, selectivity, multiplicity, and stability. A flexible model was employed for this purpose, featuring the dependence of Anderson-Shultz-Flory (ASF) factor on composition and temperature. All variabl...
